"Cloudier conditions will persist for a time in the east and south with patches of mist, drizzle and fog affecting coastal areas.

"Highest temperatures will range between 17 and 21 degrees, the warmer weather in the midlands and west."

Wednesday night will see the rain move in along the west coasts and it will be sticking around for the next few days.

The forecaster added: "On Thursday, rain will extend eastwards during the morning, becoming broken and patchy for a time in the afternoon when a clearance will develop in the west, but becoming persistent again later in the day in the east and south.

"Friday will be a largely dry day for much of the country with some good sunny spells, but there'll be showers in the west on and off through the day.

"Temperatures in the afternoon will reach between 15 and 17 degrees and winds."

The bank holiday weekend will begin in a similar vein to Thursday and Friday, there will be plenty of rain and mild temperatures.

The forecaster said: "There'll be little change on Saturday in the winds and in temperatures too, but the showers in the west will make further progress inland and will become widespread during the afternoon, some of them turning heavy at times, but they will die out again later in the evening.

"A similar day on Sunday too, light to moderate south or southwest winds with showers in the west early in the day, becoming more widespread in the afternoon and it may be just a degree or two cooler too.

"The further outlook to the early days of next week is for similar conditions with the mostly moderate southwesterly winds bringing unsettled weather."
